Error line 134

Code current:

$results = $wpdb->get_results( “SELECT * FROM $nombreTabla ORDER BY r_time DESC” );

Correct code:
global $wpdb;
$nombreTabla = $wpdb->prefix . “loginregister”;
$querypluginloginuser = $wpdb->query(“SELECT * FROM {$nombreTabla} ORDER BY r_time DESC”);
$results = $wpdb->get_results( $querypluginloginuser );
